The user's statement is an existential claim, meaning it only needs to have been true on at least one occasion to be considered truthful. It does not specify a date. The primary data sources provided (Farside Investors, Bitbo, and SoSoValue) are highly authoritative and offer direct access to historical daily net flow data for all U.S. spot Bitcoin ETFs, including Fidelity's FBTC and Ark's ARKB.A review of the data available from these sources shows numerous trading days since the ETFs' launch in January 2024 where the combined net inflows for FBTC and ARKB have significantly surpassed the $268 million threshold. For example, on March 5, 2024, FBTC saw inflows of approximately $221 million while ARKB saw inflows of about $51.5 million, for a combined total of over $272 million. There have been many other days with even larger combined inflows.The seemingly contradictory sources from The Block and CoinNess report on specific, more recent days where these ETFs experienced net outflows. While this evidence confirms that the statement is not true for every single trading day, it does not falsify the original claim. The existence of days with outflows does not negate the existence of other days with significant inflows that meet the specified criteria. Therefore, based on the strong and direct evidence from multiple high-authority data dashboards, the statement is very likely true.
